Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing wall braking mechanisms, such as those using cords or photodetector-based sensors, are either inconvenient for climbers or prone to maintenance issues and high costs.
Innovation Solution
A braking actuator mechanism that utilizes the climber's weight to actuate a switch, engaging a braking force through torque applied to the climbing panels, which includes a hinged section and a hydraulic brake to stop the climbing wall at a predetermined position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cords or photodetector-based sensors are used for braking mechanisms, then the climbing wall can be stopped at predetermined positions, but the system becomes inconvenient for climbers or requires high maintenance and costs
Solution Approach 1:
The climbing panel itself serves as the actuating mechanism. When the panel is in the lowered position, its weight and position automatically engage the braking mechanism through the cam follower and cam surface interaction, eliminating the need for external cords or photodetector sensors that require manual operation or maintenance
Solution Approach 2:
The braking function is extracted from the panel and implemented as a separate actuator mechanism that includes a cam surface, cam follower, and hydraulic brake. This separation allows the panel to simply indicate when braking is needed through its position, while the dedicated actuator handles the actual braking action, improving both reliability and ease of operation
2Reliability
If photodetector-based sensors are used for braking mechanisms, then the climbing wall can be stopped at predetermined positions, but the system incurs high costs and maintenance burdens
Solution Approach 1:
The invention replaces expensive photodetector sensors with a simple mechanical cam and cam follower system that uses the existing climbing panel structure. The cam surface is a durable mechanical component that can be manufactured at low cost and requires minimal maintenance, eliminating the high costs and maintenance burdens associated with electronic sensors
Solution Approach 2:
The system uses the climbing panel's own position and weight to actuate the braking mechanism through the cam-follower interaction. This self-actuating mechanism eliminates the need for expensive electronic sensors, controllers, and power systems, significantly reducing manufacturing costs and maintenance requirements while maintaining reliable braking function

AI summary
A climbing wall includes a frame with a guiding channel. A plurality of panels slide in the guiding channel and present a climbing surface with protrusions for climbing. The frame includes a section where the plurality of panels pivot out of the guiding channel when loaded with a climber's weight. An actuator is engaged by torque generated when one of the plurality of panels pivots out of the guiding channel. A braking mechanism is coupled to the actuator. The braking mechanism applies an arresting force to the plurality of panels when the actuator is engaged.
